Importance (% of improvement in deviance, y-axis) of the climatic variables (x-axis, for details on their meaning see Appendix S1) in the classification tree of Fig. 8, whose effect is bigger than 1%. Variables whose effect is larger than expected by chance, i.e., those whose importance is larger than 100/(number of variables), are indicated by grey shaded bars. Arrows above significant bars indicate that the climatic variable was negatively correlated with the main variable, i.e., the variable explaining the highest % of the variance. That is, if the main variable’s effect was negative, the effect of the variable indicated with an arrow was positive, or vice versa
